THE MEANING OF Q WAVE ON ELECTROCARDIOGRAM AT THE PRESENTATION OF ST SEGMENT ELEVATED MYOCARDIAL INFARCTIONBackground The aim of this study was to evaluate clinical impact of the presence of Q wave on ECG in patients with ST-segment elevated myocardial infarction (STEMI) undergoing primary ...
As seen in an ecg, no detectable p waves and irregular r-r intervals represents. meaning? A doctor has provided 1 answer A member asked: Would high calcium show up on an ecg? if so which wave would be abnormal? A doctor has provided 1 answer ...
Electrocardiographic (ECG) changes and wall motion abnormalities of the left ventricle have been observed in patients with severe intracranial hemorrhage. However, ECG evidence of an acute myocardial infarction in this setting is extremely rare but may have important therapeutic consequences. We report ...
This study examined beat-by-beat relationships between blood pressure, the time interval from the ECG Q-wave to the radial pulse wave (QRPI), and its two components, the cardiac pre-ejection period (PEP) and aortic-radial arterial pulse transit time (AR-PTT). In 8 subjects, intra-arterial...

Total Q wave duration (QWD) and amplitude (QWA) were calculated as the absolute sums of data from 12 surface leads. Results 155 patients underwent same day ECG and CMR (29±6 days post MI). QWD on ECG correlated with DE CMR infarct size (r = 0.55) and cine CMR wall motion score (...
